Used as a multifunctional monomer in the synthesis of advanced polymer networks, particularly in the development of high-performance thermosetting resins. Its four aldehyde groups enable cross-linking with amine or hydrazide compounds, forming stable Schiff base linkages that contribute to the creation of rigid, thermally stable frameworks. Commonly applied in the fabrication of porous organic polymers for gas storage and separation due to its tetrahedral geometry that promotes permanent porosity. Also explored in covalent organic frameworks (COFs) for catalysis and sensing applications, where its phenolic hydroxyl groups provide sites for metal coordination or further functionalization. Shows promise in materials science for designing nanostructured networks with tailored surface areas and chemical stability.
